摘要 目的:探讨瘦素(LEP)、可溶性瘦素受体(sOB-R)、睾酮(T)、雌二醇(E2)、卵泡刺激素(FSH)、黄体生成素(LH)在青春期肥胖儿童体内的变化规律及其相互关系,为儿童肥胖的防治提供依据。方法:以13岁的肥胖(n=79,男54例,女25例)和正常(n=85,男58例,女27例)儿童为对象,用放射免疫法测定血清LEP、T、E2、FSH、LH含量,用酶联免疫吸附分析法测定sOB-R含量,分析2组儿童间各指标的差异和相互关系。结果:肥胖儿童LEP(男(27.47±15.48)μg/L,女(33.44±15.80)μg/L)高于对照组(男(6.76±4.64)μg/L,女(10.35±5.56)μg/L)(P<0.01);男生肥胖组T((320.52±148.05)μg/L)低于对照组((398.94±154.32)μg/L),女生肥胖组E2、LH((46.03±18.68)ng/L、(15.45±7.29)IU/L)高于对照组((29.25±14.23)ng/L、(7.64±3.26)IU/L)(P<0.01)。对照组男生游离瘦素指数(FLI)与T呈负相关,与E2、LH、FSH呈正相关,肥胖组FLI仅与T呈负相关(P<0.05或0.01);对照组女生sOB-R与LH呈负相关(P<0.05),FLI与LH呈正相关(P<0.01),肥胖组女生sOB-R与T呈正相关,FLI与FSH呈正相关(P<0.05)。结论:青春期肥胖儿童体内性发育相关激素分泌水平相对于正常儿童发生了变化,男生雄性激素水平下降,女生雌性激素水平上升;肥胖儿童体内LEP水平的增高可影响体内E2、T及LH分泌的变化。 Aim:To study the changing regularity of leptin(LEP),soluble leptin receptor(sOB-R),testosterone(T),estradiol(E2),follicle stimulating hormone(FSH),and luteotrophic hormone(LH)during puberty in children and the relationship between them.Methods:The concentrations of LEP,T,E2,FSH,and LH in serum were measured respectively by the means of RIA methods and the concentrations of sOB-R in serum was measured by the means of ELISA in 164 obese(n=79,54 cases of male,25 cases of female)and normal(n=85,58 cases of male...
